HDU - 4054 Hexadecimal View (2011 Asia Dalian Regional Contest)
题意:按要求输出。第一列是表示第几行。每行仅仅能有16个字节的字母,第二列是16进制的ASCII码。第三列大写和小写转换
思路:纯模拟,注意字母的十六进制是2位
#include <iostream>
#include <cstdio>
#include <cstring>
#include <algorithm>
using namespace std;
const int MAXN = 5000; char str[MAXN]; int main() {
while (cin.getline(str, 4100)) {
int len = strlen(str);
for (int t = 0; t < len ; t += 16) {
printf("%04x: ", t);
for (int i = t; i < t+16; i += 2) {
if (i < len)
printf("%02x", str[i]);
else printf(" ");
if (i+1 < len)
printf("%02x", str[i+1]);
else printf(" ");
printf(" ");
}
for (int i = t; i < len && i < t+16; i++) {
if (str[i] >= 'a' && str[i] <= 'z')
printf("%c", str[i]-'a'+'A');
else if (str[i] >= 'A' && str[i] <= 'Z')
printf("%c", str[i]-'A'+'a');
else printf("%c", str[i]);
}
printf("\n");
}
}
return 0;
